HEEL-PLATE FOR BOOTS OR SHOES.

SPECIFICATION formingpart of Letters Patent No. 570,707, dated November 3, 1896.

Application filed May 25, 1896. Serial No. 593,018- (No model.)

To all whom it may concern:

Be it known that I, ROBERT MoKAY, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Heel-Plates for Boots or Shoes, of which the following is a specification, reference being had therein to the accompanying drawings.

It is the object of my invention to provide a means of straightening up the heels of shoes which have become worn 0163 on the edge or run over.

It is generally the case that a small portion of the heel of a shoe wears away much more rapidly than the main portion. This portion is either the rear edge of the heel,'or more frequently it extends from the rear around the outer side of the heel, and its rapid wear is due to the fact that most persons have the habit in walking of scraping the heels.

My invention consists in the peculiar con struction of adetachable heel-section covering that portion of the heel which is subject to the greatest wear and which is adapted to be easilyreversed when worn to again straighten up the heel.

In the drawings, Figure 1 is a bottom perspective view of a heel to which my device is attached. Fig. 2 is a bottom plan view thereof, and Fig. 3 is a perspective view showing the detachable heel-section reversed.

. A is the heel of a shoe of any suitable form. A portion of this heel, preferably extending approximately from the point Ct in the rear to the point I) on the outer side, is cut away and in its place is inserted the detachable heel section or plate B. This detachable section or plate is formed so that its outer edge will constitute a difierential curve, that is, a curve of gradually-increasing radii from point a to pointb, and will conform to the curve of the heel from the point a to the point I), and its inner edge will form the same curve in a reverse order, that is, having its radii increasing from the point I) to the point a. Thus a straight line joining the points a and b will divide the section into two congruent parts 0 and d.

The heel-section B is detachably secured in the recess in the heel by any suitable way, such as by the screws 0.

A shoe provided with a heel formed as described may be used until the portion 0 of the detachable section B is worn down, after which, by simply taking out the screws 0, the section may be reversed, bringing the unworn portion cl in the place of the-portion c. As the worn portion 0 will then be in the center of the bottom of the heel it will not detract from the appearance of the shoe; but, if desired, the detached section may be also reversed from the right to the left shoe,whi'ch will bring the bottom side up and thus effectually conceal the worn portion.

The section B maybe made of any suitable material, but I preferably form it of rubber,

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT MCKAY.
